It's not so much the US as it is their oil money that keeps them afloat. The shale gas boom here in the US has already cut our foreign oil dependency by quite a lot and that trend will continue. Unfortunately, China will no doubt be there to pick up the slack and keep the Saudis rolling, much like they are doing with Iran.
Eventually their oil will run out and their economy will collapse, as they have no real industry or other resources to fall back on. Only then I think will there be an opportunity for change. Still, that's likely some decades off and some of us may not live long enough to see it.
